MACHINE FOR MAKING CARPET-LINING.

Specification forming part of Letters Patent No. 14,585, dated April 1,1856; Reissued. December 11,

" 1866, Nos. 2,415, 2,416.

To all whom t may concern:

Be it known that I, JOHN R. HARRINGTON, of Dayton, Montgomery county,Ohio, have invented a new and useful Machine for Making Carpet-Lining;and I do hereby declare the following to be a full, clear, and exactdescription thereof, reference being had to the annexed drawing, makingpart of this specification.

The object of my machine is to manufacture with economy and despatch akind of carpet lining lately devised and introduced by me, andconsisting of aflap or layer of cotton batting wadding or flockinterposed between two long strips of stout paper. This lining is foundto possess in a remarkable degree the advantages of uniform and evensubstance and surface, permanent elasticity, nonconduction of air coldheat and sound, easy appliance and removal, and preservation 0f thecarpet beneath which it is spread.

In the accompanying drawing in which my machine is represented by a sideelevation (a) is the frame.

(b) are spindles hung at dierent elevations horizontally athwart theframe. These spindles (79) (b) rotate in stationary bearings (c) (c)attached to the frame.

`Around each spindle (o) (b) is wound a roll of stout paper (ci) (67').

(c) is a spindle resting (also horizontally) in oblique slots (f) so asto revolve at an elevation intermediate between the spindles Z2 Aroundthis spindle is wound a cotton bat or lap The obliquely slotted bearingof the spindle (c) enables its advance as the lap in the course ofoperation of this manufacture, becomes unwound. These parts are soarranged as represented relatively to each other as to enable the rollof wadding to rest at all times upon the lower roll of paper and to besupported and drawn onward as on an apron.

(71,) `(7L) are two rollers of which one (7M) occupies vertical slottedbearings (i) in the frame and acts as a pressure roller. To the shaft ofthe roller (71.) is applied the winch or driving pulley by which themachine is set in motion.

(j) are two rollers placed somewhat in advance of and on a level withthe rollers (71.) (h). These rollers are identical in form having eachof them two opposite ridges (7c) and grooves (Z) as represented, theridges of one roller gearing into the grooves of the other and viceversa. The circumference of each'roller including the indentations andprojections is exactly two yards, so as to measure precisely half a yardfrom each projection to the next indentation on the samerroller. Theserollerscalled by me the creasing rollers,7 in connection with a platformor box placed as described some distance immediately under the deliveryof the said rollers, serve a useful twofold purpose namely depositingthe material in uniform folds each of which represents exactly one yardlength of the stuff in other words, the stuff is thus without anyfurther manipulation, both accuratelyl measured off and convenientlyfolded for baling. This peculiar mode of folding becomes necessary fromthe nature of the material, for the paper inclosures not being of anature susceptible of stretching a continuous folding of the material inone direction-besides preventing the possibility of the above describedmethod of measurement by folds-would result in an injurious wrinkling ofone of the paper layers that would interfere with the smooth disposal ofthe lining upon a floor.

(m) is a platform which receives the lining from the creasing rollers.

(a) is a temporary front, which being held up by a pawl (0) during thefolding of the stuff, can be let down to permit the removal of the piecefor baling.

The two creasing rollers are geared together in such way as .t'o insuretheir equal action and rotation. A

(p) (70') are troughs containing vegetable mucilage; in these troughsare hung cylindrical brushes (g) (g) and are capable of rotation. Thesebrushes are, by means of counterbalances (r) made to press and revolveagainst the intended inner surfaces of the paper. The thin viscidcuticle thus imparted aords a bond of union between the outer surfacesof the filling and the inner surfaces of the paper. But when the machineis intended to manufacture a lining or wadding, without causing theintermediate layer of cotton or other filling to adhere to the outsidesheetsvof paper or cloth by means of the size or mucilage, but merely bycausing the fiber of the cotton to adhere to the rough or nappy surfaceof the paper or cloth by pressure as they are passed through the rolls72l and 71, then the troughs 19 and p that contain the adhesivesolution, and the brushes g and g that administer it, together withtheir necessary appendages may be dispensed with.

The process of manufacture is as follows: Rolls of paper and wadding,being placed in their respective bearings, as before described, and thetroughs being properly supplied with gum solution, the ends of the paperinclosures and of the wadding are introduced between the pressurerollers,

whence passing' onward they are inserted between the creasing rollers,and thence descend in proper folds as before explained onto theplatform. When the proper number of foldse-say thirtyhave accumulatedupon the plat-form the piece is separated at the proper crease by meansof shears and may then be removed and baled to make room for the neXt.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is l. The arrangement of the horizontalspindles or rollers (b and b) on which the outer sheets or rolls ofpaper or cloth are wound, in combination with the intermediate spindle(c) on which the inner layer of cotton or other filling is wound, thewhole being supported and operated in the manner, and for the purposessubstantially as described.

2. I claim the arrangement of the rolls L and it in combination with thespindles b, b, and e for the purposes substantially as herein set forth.

3. I claim the troughs p and p that contain the size or Inucilage, andthe brushes i q and g that administer it when used in combination withthe spindles and e, the whole being arranged and operating in the mannerand for the purposes substantially as specified.

4. I claim the creasing rolls y', j, when used in this connection, eachhaving alternate grooves and ridges at the requisite distance for thefolds, for the purposes of folding and measuring substantially asdescribed.

5. I claim in this connection the box or platform (m) placed below thedelivery of the rolls and having a falling front (n) as explained.

In testimony whereof, I hereunto set my hand before two subscribingwitnesses.
